不知道什么原因,贴吧时不时会冒出大盗龙科主要用嘴巴捕食的私货,然后批评大盗龙科用爪子才是私货,颠倒黑白。请宣扬大盗龙科主要用嘴巴捕食的人把相关研究贴出来吧。以下是论证南方猎龙用爪子捕食的论文:《Forearm Range of Motion in Australovenatorwintonensis (Theropoda, Megaraptoridae)》南方猎龙因为化石保存得比较好,是大盗龙龙科研究最透彻的物种。链接:百度网盘

部分内容摘抄如下:
论文摘要就写了用手脚杀死猎物,1-2指爪起主导作用 :We envision that prey was dispatched by its hands and feet with manual phalanx I-2 playing a dominant role.
论文讨论明确说了,其他较大的兽脚亚目用手控制猎物,然后用嘴咬,然而南方猎龙的前臂横向伸展运动可能代表了一种有助于捕获猎物的捕食性行为。The forearm ROM comparisons of Australovenator with other theropod groups provide insight into the functional role the forelimb played during prey capture and dispatch. Larger theropods such as tyrannosaurids and carcharodontosaurids possessed limited anterior reach suggesting that initial prey capture was made orally with the forearms used to maintain grip on prey. The forearm lateral extension mobility of Australovenator possibly represented a predatory action that facilitated prey capture.
论文讨论部分:南方猎龙有一个细长的齿骨,因此很可能咬合相对较弱。 Australovenator had a gracile dentary and most likely possessed a relatively weak bite as a consequence.
论文结论第一句:南方猎龙的前臂在捕获猎物方面发挥了主导作用。The forearms of Australovenator are envisioned to have played a dominant role in prey capture. have played a dominant role in prey capture.
